High-quality materials and construction
Whether it’s a remote mining camp, a critical healthcare facility, a data centre, or a modular building on site — Larnec modular doors are engineered and manufactured to perform. Built tough, customised to spec, and backed by proven Australian manufacturing, our doors help protect people, assets, and environments across industries.
Designed for Demanding & Controlled Environments
Mining & Remote Site Applications
In mining and remote operations, durability isn’t optional — it’s essential. Our modular doors are engineered to withstand heavy use, vibration during transport, dust, heat, wind loads and harsh site conditions.
Ideal for:
- Accommodation units
- Crib rooms & site offices
- Switch rooms & plant buildings
- Ablution blocks
- Workshops and service buildings
Built tough, pre-hung for efficient installation, and manufactured to integrate seamlessly with modular wall systems, Larnec doors help maintain safety, security and operational continuity on site.

Healthcare & Controlled-Environment Applications
Precision environments demand reliable separation and hygiene control. Our modular door systems support hospitals, laboratories, cleanrooms and medical facilities with:
- Smooth, easy-to-sanitize finishes
- Compatible vision panels
- Tight sealing for environmental control
- Insulated cores for thermal performance
Designed to integrate with insulated panel systems, these doors help maintain controlled internal conditions without compromising durability.

Mission-Critical & Secure Areas
For data centres, battery rooms, communications hubs and secure infrastructure spaces, door performance plays a critical role in asset protection and operational resilience.
We offer:
- Enhanced perimeter seals
- Thermal and insulated core options
- Heavy-duty hardware configurations
- Access control compatibility
- Fire-rated solutions where required
Each door set is configured to suit your wall construction and performance specification — ensuring reliability in high-consequence environments.
